| 摘 要： | 笔者对国内外同位素测定年在确定油气成藏方面的应用现状进行评述的基础上,重点分析了K-Ar法,Ar-Ar法,U-Pb法,Rb-Sr法等方法所存在的问题,认为自生伊利石40Ar-39Ar法在不断克服技术难题之后,仍是油气成藏年代学不可缺少的重要手段;激光微区探针40Ar-39Ar法与流体包裹体技术相结合,是油气多期成藏40Ar-39Ar年代学研究取得成功的突破点;利用沥青和干酪根中微量金属U-Pb,Pb-Pb,Rb-Sr,Sm-Nd和Re-Os体系的同位素分析方法获得油气生成、运移的年龄,是成熟的放射性同位素方法在石油地质学中的应用;晶洞充填物U-Pb测年,可能是碳酸盐岩储层油气成藏年代学研究又一新的突破点.

| Abstract: | The present paper gives a general review of the isotopic dating techniques including K-Ar,Ar-Ar,U-Pb and Rb-Sr methods and their applications to the geochronology of hydrocarbon migration and accumulation in China and foreign countries.With the innovation and development,the authigenic illite 40Ar-39Ar method is still an indispensable technique in the chronology of hydrocarbon migration and accumulation.The integration of fluid inclusion technique and authigenic K-feldspar laser microprobe 40Ar-39Ar dating ... |
